MOVABLE FROG.

Specification of Letters Patent.

Patented July 3, 191?.

Application filed June 1, 1916. Serial No. 101,050.

To all whom it may concern:

Be it known that I, ANTHONY L. VIssAT,

a citizen of the United States, residing at Herminie, county of Westmoreland, and State of Pennsylvania, have invented certain new and useful Improvements in Movable Frogs, of which the following is a specification.

This invention relates to railway frogs and has for its object to provide as an ele ment of the frog, a removable frog block for transferring a train from one track'to another and to further provide means, in, a manner as hereinafter set forth, associated with the movable frog block for locking the latter in the position to which it has been shifted.

Further objects of the invention are to provide a railway frog which is simple in its construction and arrangement, capable of being used in connection with steam and electric railways, strong, durable, efficient in its function, conveniently operated, readily set up with respect to a railway track, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, .combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a top plan view of a railway track showing the adaptation therewith of a frog in accordance with this invention.

Figs. 2 and 3 are details of a movable frog plate.

Figs. 4 and 5 are sectional details of the shifting means for the movable frog.

Fig. 6 is a top plan and Fig. 7 an end view of a movable frog plate.

Referring to the drawings in detail 1 denotes a seriesof ties for supporting the track rails forming a pair of tracks at a crossing or frog and the rails of one track are indicated at 8, 4, 5, 6, and 7. The rails are positioned in longitudinal alinement and with the rails 5 and 6 spaced from each other. The rails of the other track are in dicated at 8, 9, 10,11 and 12. The rails 9 and 12 are disposed at an inclination and are arranged in alinement and with the rails 10 and 11 spaced from each other.

The rails 6 and 11 are formed integral with the extension 13 of a movable frog supporting plate 14. The inner ends of the rails 6 and 11 merge into each other. The rails 5 and 10 are formed integral with the extension 15 of the plate 14. The extensions 13 and 15 project in opposite directions with respect to each other and are disposed eccentrically with respect to the longitudinal center of the plate 14.

The extension 13 has formed integral therewith a filler member 16 which projects beyond the outer end of the plate 13 and said filler member 16 is interposed between the rails 6, 7, and 11 and 12. The filler member is seated upon the bases of the rails 7 and 12, and abuts against the webs thereof and also against the lower face of the heads.

Formed integral with the extension 15 and projecting beyond the outer end thereof is a filler member 17 which is interposed between the rails 4 and 5 and 9 and 10 and is mounted upon the bases of said rails, and abuts against the webs and also against the lower faces of the heads.

The filler members 16 and 17 constitute what may be termed braces for rails.

The plate 14 between its center and each end is formed with a transverse slot 18, and each side wall of the latter, at each end thereof is notched, as at 19, for a purpose to be presently referred to. The plate 14 is also provided with openings for the passage of spikes to fixedly secure the plate to the cross ties.

Fixed to one of the ties, that tie disposed centrally with respect to the plate 14 and which tie is indicated at 20, is an elongated flanged bearing plate 21. The flanges of the plate 21 are indicated at 22 and are positioned at the sides of the tie 20. Arranged at each side of the bearing plate 21 and moving against the flange 22 thereof is a shifting arm 23 which is offset intermediate its ends as at 24, and has its inner end bifurcated, as indicated at 25. One wall of the furcation is of less length than the other wall and that wall of less length is indicated at 26. The rear wall of the furcation extends at an inclination, as indicated at 27.

Mounted upon the bearing plate 21 and overlapping the outer ends of the shifting arm 23, is a reciprocatory cross-head 28 which is connected, by the securing devices 29, to the shifting arms 23. The cross-head 28 has an upwardly extending lug 30,7which is loosely connected, as at 31, to the arm 32, of a bell crank lever is attached to an actuating means 34 therefor. The bell crank lever is pivoted as at 35, upon'a plate 36, which is secured to a tie indicated at 37.

Projecting outwardly from the cross-head 28, is a rod 38 which is provided with an opening through which is adapted to extend a locking pin 39 to arrest the cross-head 28 from movement. The rod 38 projects through a casing 40 and between a pair of guides 41. The casing is secured to the tie 20. The locking pin extends through the casing 40.

When the cross-head 28 is shifted to the position shown in Fig. 1, the pin 39 extends through the rod 38 and looks it in such position and when the cross-head is shifted to the limit of its movement the pin 39 is also adapted to extend through the rod 38, so as to lock the cross-head. The reference character 42 denotes a shifting means for the pin 39.

Mounted upon the plate 14 is a shifting frog plate 43, which is provided with track rails.44 and 45, and which have depending from their lower face a pair of elongated lugs 46, having side grooves 47, into which extend the arms 48, 49, formed by the bifurcated inner end of the shifting arms 23. The arms 48, 49, are'secured to the lugs 46 by bolts and nuts 51. The arms 48 and 49 project outwardly from the grooves 47,

as clearly shown in Fig. 3. The lugs 46 extend down through the slots 18 and are secured to the bifurcated inner endsof the shifting arms 24 by the bolt 50 and nuts 51.

' When the plate 43 is in the position shown in Fig. 1, the rail 44 is interposed between the rails 5 and 6, so as to form a continuation of the said rails and the rolling stock will be directed to travel on the track formed by the rails 3, 4, 5, 44, 6 and 7. If the plate 43 is shifted from the position shown in Fig. 1, so as to aline the rail 45 with the rails 10 and 11, the rolling stock will be directed to travel upon the track formed by the rails 9, 10, 45, 11, 12 and 8.

A movable frog for railways comprising a supporting plate provided with oppositely disposed extensions each having its upper face formed with a pair of track members extending in different directions, said plate further having a pair of transverse slots, a shiftable frog plate sliding 011 said supporting plate and provided with depending lugs extending through said slots, a pair of shifting arms having bifurcated inner.
